I have more acryllic paint ranges than I care to remember. I tend to stick to Vallejo as it thins well with water and has good coverage overall. Huge range of colours and you can always find what you want between their ranges. I like the lack of bad smells and I feel safer if I get a whiff of them than I do more toxic paints. I'm a mini painter so being good for hand brushing is my biggest priority with everything else coming second to it. If I was recommending someone a paint range Vallejo would be my recommendation. It's very hard to ruin a kit with them and you can use tap water to thin them keeping costs dirt cheap. They come in every colour of the rainbow, aren't terribly difficult to air brush, are great value for money and they don't react with anything you want to put over the top of them.
While I have my preference I realize every tool has it's place and you shouldn't get into internet slap fights over your preference. There's effects only enamels can do, only oils can do and only acrylics can do. The right tool for the job is the tool that gets the job done in a way you like while not harming the kit. There's no reason you can't mix and match different types of paints and it's only handicapping yourself to do so. If your wallet can take the hit (and who doesn't like buying some new paint?) then I'd highly recommend exploring multiple paint ranges and paint types. Enamel washes from MIG and AK have revived enamels from the stuff no one uses as it's outdated and hard to work with into a common as muck weathering technique (I'm talking in my area of modeling, not saying some older folks don't like enamels and haven't stuck with them as other paint technology improved). Oils are now beginning to get mainstream attention in arenas outside of military modeling. Even though my main focus is science fiction and fantasy I realize each branch of the modeling tree does things slightly differently and you always have more to learn and explore. All to often we end up rumour mongering or drawing battle lines which really aren't needed, it's human nature but as someone who used to swear off enamels as being unhealthy to use I've realized I was being a bit of a plonker and added them into my tool box.
